PORN legend Candida Royalle still loves writing and directing adult films – but it’s taken a sad toll on her sex life. “I have absolutely no time for it anymore. I’m just working too much. And I’m engaged,” said Royalle, whose comedy “Under the Covers” hits stores today. Her hip-hop flick, “AfroDite Superstar,” is out next month. Also busy training a stable of young women filmmakers to get into the business, she told us: “It sounds crazy I know, but I’m going to have to take a break from the sex industry – just so I can have time for sex.”
